Flare Activity and Magnetic Feature Analysis of the Flare Stars II: Sub-Giant Branch

Hadis Goodarzi, Ahmad Mehrabi, Habib G. Khosroshahi +1

We present an investigation of the magnetic activity and flare characteristics of the sub-giant stars mostly from F and G spectral types and compare the results with the main-seque…

Flare Activity and Magnetic Feature Analysis of the Flare Stars

Hadis Goodarzi, Ahmad Mehrabi, Habib khosroshahi +1

We analyze the light curve of 1740 flare stars to study the relationship between the magnetic feature characteristics and the identified flare activity. Coverage and stability of m…

Activity Analyses for Solar-type Stars Observed with Kepler. II. Magnetic Feature Versus Flare Activity

Han He, Huaning Wang, Mei Zhang +3

The light curves of solar-type stars present both periodic fluctuation and flare spikes. The gradual periodic fluctuation is interpreted as the rotational modulation of magnetic fe…

Magnetic activity analysis for a sample of G-type main sequence \emph{Kepler} targets

A. Mehrabi, H. He, H. Khosroshahi

The variation of a stellar light curve owing to the rotational modulation by the magnetic features (starspots and faculae) on the star's surface can be used to investigate the magn…

On the possibility of magnetic field detection on a microlensed source star

Ahmad Mehrabi, Habib khosroshahi, Hadi Rahmani

In a microlensing event, a large magnification occurs at caustic crossing and provides an opportunity to obtain a stronger signal associated with the object. In this paper we study…

Compact object detection in self-lensing binary systems with a main-sequence star

S. Rahvar, A. Mehrabi, M. Dominik

Detecting compact objects by means of their gravitational lensing effect on an observed companion in a binary system has already been suggested almost four decades ago. However, th…
